[TowerTalk] Oil For Dummy Load

[Martin A Flynn]

The C84025-1 Coaxial Dynamics load (2.5 kW CCS) at our club station uses 
Dow-Corning Xiameter PMX-200 silicon fluid.

A gallon was less then $50.00.    We would have went with Diala ZX-4 
transformer oil, but could not find reliable information if the residual 
silicon fluid  would safely mix with the Daila.

In either case, the right part is fairly inexpensive - why  use a 
substitute?

You need _every bit of advantage_ you can get.  As it is, those DLs are rated a kilowatt for only a few seconds. That's why I stopped using my HN31 with an amplifier, and built my compact 1500W (100% D/C) load.
